We investigated the relaxation dynamics of Xenon and Argon dimers employing momentum coincidence spectroscopy at the reaction-microscope beamline FL26 at FLASH2. Using the grazing incidence split, delay and focusing optics, a XUV-XUV pump-prope scheme was utilized to track dissociation dynamics. On the poster we present results for different relaxation channels, e.g. Interatomic Coulombic decay (ICD) or charge transfer.
